•

same flow ratios and control characteristics for “hard” valve seats (metal-to-metal) and “soft” valve seats (metal-gasket), for valve plugs, balanced and unbalanced,

•

reliable actuator-stem and valve seat-body connections,

small guiding sleeve control forces due to application of balanced valve plugs in valves DN40…250,

•

top-class flat and bonnet packings,

•

wide range of electric actuators,

•

possibility of mating with NN type hand operated drives,

•

possibility of special executions for oxygen, hydrogen, gas fuels, low temperature mediums (liquid oxygen, liquid nitrogen), acid gases containing H₂S; explosive atmospheres as per 94/9/EC - ATEX,

•

competitive prices – due to simple and functional design of valves and actuators and applied materials,

•

design and production process meets the requirements of Quality Management System ISO 9001 and Directive 97/23/EC, and regulations of AD2000 Merkblatt, designated for installation on pipelines, Z ® is a trademark registered with Republic of Poland Patent Office.

Table 14. Available force F_S [kN] of pneumatic actuators

NOTE:

1. For direct actuators P adopted spring range is 20 – 100 kPa

2. For electric and other actuators Δp value can be calculated using above formula and data from Tables 12 and 14, taking nominal load capacity as available force F_S, as per actuator catalog chart.

3. For balanced valve plugs available force Fs at least equal to F_D value for soft valve seats in Table 12 should be adopted.

ALLOWABLE PRESSURE DROPS ∆p.

Pressure drops ∆p [bar] in Tables 15 and 16 apply to closed valve and they are calculated for valve drive poten- tial. Actual pressure drops should not exceed 70% of allowable working pressure for given nominal pressure, material execution and working temperature, as per tables 5…11.

Table 16. Allowable pressure drops ∆p [bar] for valves with unbalanced valve plugs and soft valve seats, with pneumatic actuators. Note: 1. In Table 15, theoretical acceptable pressure drops are included. Actual pressure drops with consideration of tolerance of

spring manufacture and friction of internal parts of the actuator are lower than those given by 20%. Pressure drops chosen that way guarantee internal tightness of closing of the valves.

2. In air-to-open valves actuator with spring range of 40-200 [kPa] can be replaced with actuator with spring range of 40-120 [kPa], at the same pressure drops.

3. In valves with balanced valve plugs and hard valve seats for pressure drops up to Δp=40 [bar], actuators are to be selected as below:

- for air-to-close action: spring range 20-100 [kPa], supply pressure 140 [kPa] - for air-to-open action: spring range 40-120 [kPa], or 40-200 [kPa]

VALVE DRIVES:

1. Diaphragm multi-spring pneumatic actuators w/o manual drive type P/R or with top-mounted handweel type P/R-N – as per Tables 17 and 20.

Table 17. Pneumatic actuators

CHARACTERISTICS:

- complete reversibility of operation allows changing function P (direct action) and R (reverse action) with no additional parts,

- option of changing spring range (tension) with no additional parts, - option of pre-tensioning of springs,

- option of fitting with top-mounted handweel. DESIGN AND TECHNICAL SPECIFICATION: As per Fig. 5.

CONSTRUCTION:

Actuator diaphragm cases (1) and (2) of steel sheets making pressure chamber

Diaphragm (3) of constant effective area, linear relationship between control actuator pressure and plug movement. Executed in neoprene with polyester spacer.

Diaphragm plate (4) stamped from steel sheet, with spring seats. Support (6) is used for tightening and operating the stem.

Springs (7) of construction spring steel. There are 3, 6 or 12 springs regarding the required range.

Bushing (8) and spacers (9) – used for altering actuator action from direct to reverse and altering spring range.

Warning plates (10) with information on safe disassembly. TECHNICAL SPECIFICATION:

Control air connection: NPT 1/4”, NPT 1/2” Pipe diameter: ∅ 6x1, ∅ 8x1, ∅ 10x1, ∅ 12x1

Spring ranges: 20…100 kPa; 40…120 kPa; 60…140 kPa - 3 springs, 40…200 kPa; 80…240 kPa; 120…280 kPa - 6 springs,

180…380 kPa - 12 springs; (only sizes 630-1000).

Optional accessories: - top-mounted handweel, - pneumatic positioner, - electro-pneumatic positioner, - air-set,

- three-way solenoid valve, - lock-up,

- limit switches, - quick exhaust valve.

Note:

1. In Table 16, theoretical acceptable pressure drops are included. Actual pressure drops with consideration of tolerance of spring manufacture and friction of internal parts of the actuator are lower than those given by 20%.

Pressure drops chosen that way guarantee internal tightness of closing of the valves.

2. In air-to-open valves actuator with spring range of 40-200 [kPa] can be replaced with actuator with spring range of 40-120 [kPa], at the same pressure drops.

3. In valves with balanced valve plugs and soft valve seats for pressure drops up to ∆p=35 [bar],actuators are to be selected as below:

- for air-to-close action: spring range 20-100 [kPa], supply pressure 140 [kPa] - for air-to-open action: spring range 40-120 [kPa], or 40-200 [kPa]

4. For rotary actuators – R, supply pressure is to be 40 kPa higher than upper spring range [kPa].
